There is a lot of good information here. This is the first time I am hearing of this layout, and I am not intrigued.
I am French, and typed on a AZERTY layout until I was 20. I then moved to the UK, back to France, UK again, then Canada, France, Canada, France, USA, France, USA. with at least 6 months in country each time. 6 months in which I learned QWERTY, then relearn AZERTY, and back and forth. After much frustration, I started to always move with 2 AZERTY keyboards ( home and work), and finaly learned how to type without loooking at the keys. So my work laptop is a QWERTY layout which types like an AZERTY (half of the emails I type are still in French and I need the accens), which not unlike what you mentioned above, frutrates other people trying to use my computer (espacially our IT department) even though there are not so many keys out of place.
How do you learn and use Dvorak? Did you buy a Dvorak layout for visual aid, or did you start directly by reprogramming the keys? Did you have any problem with the numbers being non-sequencial?
The are two versions of the French Dvorak, I think I’d give them both a try (and interestingly enough, both versions have numbers arranged sequencially). I’m a little bummed that the iPad does not seem to support this layout though…
